quagga 0.99.20-3 (i386 binary) in ubuntu precise

GNU Quagga is free software which manages TCP/IP based routing protocols.
It supports BGP4, BGP4+, OSPFv2, OSPFv3, IS-IS, RIPv1, RIPv2, and RIPng as
well as the IPv6 versions of these.
.
As the precessor Zebra has been considered orphaned, the Quagga project
has been formed by members of the zebra mailing list and the former
zebra-pj project to continue developing.
.
Quagga uses threading if the kernel supports it, but can also run on
kernels that do not support threading. Each protocol has its own daemon.
.
It is more than a routed replacement, it can be used as a Route Server and
a Route Reflector.
